Department of Ultrasound, Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine, Shanghai, China. Electronic address:
Objective: To evaluate the added value of dynamic contrast-enhanced ultrasound (DCE-US) analysis in pre-operative differential diagnosis of small (≤20 mm) solid pancreatic lesions (SPLs).
Methods: In this retrospective study, patients with biopsy or surgerical resection and histopathologically confirmed small (≤20 mm) SPLs were included. One wk before biopsy/surgery, pre-operative B-mode ultrasound and contrast-enhanced ultrasound were performed.
Background: Alzheimer's disease (AD) is a progressive neurodegenerative disease and the most prevalent type of senile dementia affecting more than 6 million Americans in 2023. Most of these AD cases are sporadic or late-onset AD with unclear etiology. Recent clinical trials on antibody drug clearing Ab plagues in brain show modest benefits of slowing down cognitive decline.

Background: Limbic-predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) denotes TDP-43 deposition in older age and is consequential for cognitive function. Currently there is no way to identify LATE-NC during life. Some forms of TDP-43 deposition in younger age, related to frontotemporal dementia (FTD), are associated with pronounced asymmetrical atrophy of the temporal lobe.

NYU Grossman School of Medicine, New York, NY, USA.
Background: Down syndrome (DS) is strongly associated with Alzheimer's disease (AD), attributable to APP overexpression, displaying common features with early-onset AD (EOAD) and late-onset AD (LOAD) like Amyloid-β (Aβ) and tau pathology. Here, we evaluated the Aβ plaques proteome of DS, EOAD and LOAD.
Method: We used unbiased localized proteomics to analyze amyloid plaques and the adjacent plaque-devoid tissue ('AD non-plaque') from post-mortem paraffin-embedded tissues in three subtypes of AD (n = 20/group): DS (59.

Alzheimers Dement
December 2024
Delaware State University, Dover, DE, USA.
Background: Aggregation of transactive response DNA binding protein 43 (TDP-43) is the major pathological feature of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Recently, in up to 50% of Alzheimer's disease (AD) cases TDP-43 pathology was discovered and this pathology has been referred to as limbic-predominant age-related TDP43 encephalopathy (LATE). Several studies reported that TDP-43 binds to heat shock protein family B (small) member 1 (HSPB1 or HSP27) but no functional evaluation of this interaction has been explored.
